The service, formally named Multimedia Educational Resource for Learning and Online Teaching, provides access to a resource collection and instructional resources to support online instruction, including course outlines, speaker notes, learning assessments, and study notes. Varying access levels include basic and advanced search for materials, search across membership lists, development of personal collections, and contribution of both new materials and comments on existing ones. API methods support search against the MERLOT resource collection, either single-box keyword match or advanced search against specific data fields. Methods also support compiling custom personal resource collections and contributions of new materials, either information sources or instructional aides, to the collection.
